如何取得一个像素点的颜色？

我想返回鼠标点击的点的颜色，怎么办？

[hello_wyq]

using
getRGB()

如果你说的是Color.getRGB()，那么不跟没说一样么？
我现在就是不知道Color。

int imageWidth = image.getWidth(this);
int imageHeight = image.getHeight(this);
int[] pixelArray = new int[imageWidth * imageHeight];

public ImageHolder() {
try { grabber.grabPixels(); }
catch(InterruptedException ie){
System.out.println("Pixel array not completed");
return;
}

addMouseListener(new MouseAdapter(){
public void mouseClicked(MouseEvent me){
int mouseX = (int)me.getPoint().getX();
int mouseY =(int) me.getPoint().getY();
int pixel = pixelArray[(mouseY * imageWidth) + mouseX];
getPixel(pixel);
}
});

setSize(imageWidth,imageHeight);
}

public void paint(Graphics g){
int xCenter = (getSize().width / 2) - (imageWidth / 2);
int yCenter = (getSize().height / 2) - (imageHeight / 2);
g.drawImage(image, xCenter, yCenter, imageWidth, imageHeight, this);
}

public void getPixel(int pixel){
int alpha = (pixel >> 24)&0xff;
int red = (pixel >> 16)&0xff;
int green = (pixel >> 8)&0xff;
int blue = (pixel)&0xff;
System.out.println( "("+alpha+","+red+","+green+ ","+blue+ ")");
}
}
